Research Abstract

^4He crystals were blown off by acoustic radiation pressure and floated in the superfluid under the reduced gravity condition. Apiece of stainless steel buried in a^4He crystal was driven by the inch-warm method of piezo crystal. We succeeded in operating the piezo crystal at very low temperatures and are ready to apply it to He crystals. Crystallization of He was investigated in aerogels and self-organized criticality in quantum tunneling was discovered.
